I've just got back in Ragnarok not long ago at all and I've finally got a max char to pvp around with against the friends and stuff for fun and for the experience. One thing that totally annoyed me was how much delay there are in between the skills that you cannot use and having to wait in order to use any other skills. Like for example; keen nose;... upon using that skill, you cannot use any skills whatsoever (it gives off; "skill can't be cast" warning) until literally about 2 seconds cooldown (which feels SUPER LONG in pvp), in order to use any other skills. This includes a lot of other skills such as Ward Rider, as well, that I don't see a purpose of having every other skill to have delay (unable to cast) untill the cooldown ends.
I really say, please no all-skill delay when using some of these skills. Isn't this game suppose to be a 'skilled' based game and not just "spam that skill" game?
